Brake Caliper: Assembly

Clamp caliper in vise. Dip new piston seal in lubricant (supplied with kit) Ucon #LB1145Y24 (or equivalent) and install in groove in bore. Coat new piston boot with lubricant leaving a generous amount of lubricant inside of boot. Install in caliper by working into outer groove, using fingers only. Plug high pressure inlet to caliper and bleeder screw hole, then coat piston with generous amount of lubricant (as specified above). With fingers spreading boot, work piston into boot and press down on piston. The trapped air below piston will force boot around piston and into its groove as piston is depressed. Remove plug and carefully push piston down bore until bottomed. Install inner guide pin bushing in caliper with flanged end on inboard side. Compress flanges of outboard bushing with fingers and work into position in hole from outboard side of caliper. Press in on bushing, using fingers or small plastic stick until seated.
